Purpose: This study aims to provide preliminary data for weight management, and prevention and management of cardiovascular and cerebrovascular diseases. We examined the effect of changes in the weight of workers at a manufacturing company over three years on their metabolic syndrome and metabolic syndrome diagnosis components. Methods: Necessary data were collected from the questionnaire and the results of the Korean National Health Screening of 2015 and 2017, which included 228 workers at a manufacturing company in G region. The collected data were analyzed using the SPSS/WIN 23.0 program. ANCOVA was used to examine the differences in the metabolic syndrome diagnosis components according to weight change. In addition, multiple logistic regression analysis was used to obtain the odds ratios of metabolic syndrome and metabolic syndrome analysis component, based on the weight changes in the normal weight group and the obesity group. Results: Waist measure, systolic blood pressure, and blood pressure were found to have significant effects based on participants' weight change over three years. These factors increased with a larger increase in weight at a statistically significant level. This study analyzed the weight changes of the normal weight group and the obesity group considering the data from the National Health Screening of 2015, and found that the risk of metabolic syndrome increased at a statistically significant level as body weight increased; thus, the obesity group showed a higher risk in this regard. It was also found that waist measure, fasting blood sugar, and high-density low cholesterol increased at a statistically significant level as body weight increased. Conclusion: Health administrators need to recognize the importance of workers' weight management, select an intensive management group based on a time series analysis of weight changes, and develop and implement programs to manage the metabolic syndrome diagnosis components.

This study aimed to evaluate the effects of exposure to manganese (Mn) and lead (Pb) on immune system. The subjects were 42 male workers, among whom 13 office workers (Group I) had never been occupationally exposed to heavy metals, 21 were worked in manufacturing factories (Group II) and 8 were welders (Group III). The mean blood Mn and Pb level by groups were significantly different. The numbers of CD19+ and total lymphocytes in Group I were significantly higher than those in other groups, but no significant differences were found in other T lymphocytes subpopulation. Mn and Pb concentrations showed negative correlation with T lymphocytes subpopulation, but Mn concentrations were statistical significances with T lymphocytes subpoplation except CD4+CD45RO+ and natural killer cell. Pb concentration was only statistical significance with total lymphocytes. Our results suggest that occupationally exposed to Mn and Pb can affect the cellular immune response.

In modern industrial capitalism, the relationship between the provision of work and the receipt of wages has become an important principle governing society. According to the labor contract, the wages provided by entrusting the right to dispose of one's labor to the employer are directly compensated, and human life should be guaranteed and reproduced with proper rest. The establishment of labor relations under free contracts represents a problem in protecting workers, and accordingly, the maximum of working hours is set as a minimum right for workers, and the standard for minimum rest is set and assigned. The reduction of working hours is very important in terms of the quality of life of workers, but it is also an important issue in efficient corporate activities. As of 2020, Korea has 1,908 hours of annual working hours, the third lowest among OECD 37 countries in the happiness index surveyed by the Sustainable Development Solution Network(SDSN), an agency under the United Nations. Accordingly, the necessity of reducing working hours has been recognized, and the maximum working hours per week has been limited to 52 hours since 2018. In this situation, various working hours are legally excluded as a way to maintain the company's value-added creation and meet the diverse needs of workers, and Korea's Labor Standards Act restricts flexible working hours within three months, flexible working hours exceeding three months, selective working hours, and extended working hours. However, in the discussion on the application of the revised flexible working hours system in 2021 and the expansion of the settlement unit period recently discussed, there is a problem with the flexible working hours system, which needs to be improved. Therefore, this paper aims to examine the problems of the flexible working hours system and improvement measures. The flexible working hours system is a system that does not violate working hours even if the legal working hours are exceeded on a specific day or week according to a predetermined standard, and does not have to pay additional wages for excessive overtime work. It is mainly useful as a form of shift work in manufacturing, sales service, continuous business or electricity, gas, water, and transportation for long-term operations. It is also used as a way to shorten working hours, such as expanding holidays through short working days. However, if the settlement unit period is expanded, it is disadvantageous to workers as the additional wages that workers can receive will not be received. Therefore, First, in order to expand the settlement unit period currently under discussion, additional wages should be paid for the period expanded from the current standard. Second, it is necessary to improve the application of the flexible working hours system to individual workers to have sufficient consultation with individual workers in a written agreement with the worker representative, Third, clarify the allowable time for extended work during the settlement unit period, and Fourth, limit the daily working hours or apply to continuous rest. In addition, since the written agreement of the worker representative is an important issue in the application of the flexible working hours system, it is necessary to secure the representation of the worker representative.

This study was performed to determine the musculoskeletal symptoms and its association with sociodemographic and health related characteristics, job-related characteristics and occupational stress among manufacturing workers. The self-administered questionnaires were given to 856 male workers in randomly selected 62 work places with 50 or less employees in manufacturing industries during the period from October 1st, 2011 to November 30th, 2011. Complaint rates of work-related musculoskeletal symptoms was 82%. In logistic regression analysis, significant factors related with musculoskeletal symptoms were marital status, BMI, subjective health status, alcohol drinking, job position, job tenure, experience of sick absence and visiting out-patient department. In conclusion, the study results suggested that the complain rates of work-related musculoskeletal symptoms of workers in work places of manufacturing industries with 50 or less employees were higher than workers in a large enterprise or the small and medium enterprises and it was related with sociodemographic and health related characteristics, job-related characteristics and occupational stress.

This study examined the fatigue and its association with job stress among male workers engaged in small-scale manufacturing industries. The study subjects were 553 male workers under 50 members of manufacturing industries. The study survey was a structured questionnaire of the Korean Occupational Stress Scale (KOSS) and Multidimensional Fatigue Scale (MFS) during April, 2015. The data were analyzed using the SPSS ver 21.0 program. The results showed that the high risk fatigue group was significantly higher in the high risk group of job stress than in the normal group of job stress. Fatigue was positively correlated with job stress. The odds ratio of the high risk fatigue group were increased significantly in the high risk group of job stress than in the normal group of job stress. The factors of influence with explanatory powers of 27.7% on fatigue included age, marital status, educational level, subject health status, sleeping time, drinking coffee, job tenure, shift work, visiting out-patient department, sense of satisfaction in job life, and job stress. Fatigue was associated with the sociodemographic characteristics, health behavior related characteristics, job-related characteristics, and job stress.

Traditionally, foreign labor inflow into Korea has been rare and, hence, issues on foreign workers did not draw much attention. However, changing economic conditions of the Korean economy, such as "labor-shortage" problem in SMEs in manufacturing sector, has made the Korean government open its door to the foreign workers since the early 1990s through the Industrial Trainee System. The inflow of foreign workers, on the other hand, has generated various social and economic problems, such as substantial increase of illegal over-stayers, illegal utilization of foreign unskilled workers by domestic SMEs, to name a few. Against this background, the Employment Permit System was implemented from 2004. This new system aims at supplying foreign workers to SMEs as well as protecting them as legal 'employees'. In any case, it is very important to understand how and to what extent the inflow of foreign workers have affected the Korean economy in order to establish long-term policy stance. This paper aims to empirically assess the economic impact of foreign workers on domestic workers in the manufacturing sector during 1997~20001, focusing on the Industrial Trainee System. The empirical results of the paper can be summarized as follows. First, there is some evidence that male semi-skilled workers are the group that is likely to have been displaced by industrial trainees. Second, we were unable to find any strong evidence suggesting that the inflow of foreign industrial trainees decreased wages of less-skilled Korean workers.

The purpose of this study was to investigate the effects of safety culture on the safety consciousness and safety behaviors of manufacturing workers, and to suggest ways for manufacturing workers to understand the safety culture and improve safety consciousness and safety behavior. To achieve this research objective, out of 176 industrial complexes in Seoul and Gyeonggi Province registered with the Korea Industrial Complex Corporation, workers at 50 industrial complexes, including the Korea Export-Industrial Complex and Seoul's Onsuji, were subject to research. The implementation of this survey distributed 300 questionnaires through the mid-level managers of manufacturers and environment safety and health managers over a period of one month from August 1st to 31st, 2019, finally statisticalizing the data in 282 parts excluding 18 questionnaires deemed to have been unresponsive. First, the safety culture (safety climate, safety procedures) has a positive effect on the safety consciousness (recognition of importance, interest and participation inducement) of the manufacturing workers. Second, the safety culture (safety climate, safety procedures) has a positive effect on the safety behavior (safety planning, safety check) of manufacturing workers. Third, safety consciousness (recognition of importance, interest and inducement of participation) has a positive influence on the safety behavior (safety planning, safety check) of manufacturing workers. Fourth, the safety consciousness (recognition of importance, interest and inducement of participation) appears to have a partial mediating effect in relation to safety culture (safety climate, safety procedure) and safety behavior (safety planning, safety check) of manufacturing workers. The implication of this study is that although the industrial accidents have occurred in the manufacturing industry in recent years, the studies on the workers in the manufacturing industry are insufficient. However, this study is meaningful that it has suggested ways for manufacturing workers to understand the safety culture and improve the safety consciousness and safety behavior by analyzing the effects of safety culture on safety consciousness and safety behavior of manufacturing workers.

For the purpose of grasping the actual condition of low back pain in women workers, 166 women in two neighboring factories were studied using questionnaire, 60% of the workers complained of low back pain. and 63% of them responded that their low back pain come from their job. About the severity, 77% marked the moderate, and 15% said absences owing to the pain. But 60% of them have not sought medical help. The low back pain occurred mainly in the workers of sitting posture and in the workers of treating heavy objects. And the workers who have worked over three years are dominant(44%) in the pain group. Comparing the pain group with the non-pain group, two variables - whether the worker treats heavy materials or not, and how heavy the materials are - showed statistically significant differences. So. there must be concern over the low back pain of women workers. In operation allocation. treating heavy objects and lifting up should be carefully considered. And for the prevention of low back pain. the workers need education and pain exercise.

Purpose: The purpose of this study was to develop and test a structural model on cardiovascular disease risk factors among male manufacturing workers. Methods: Data were collected through questionnaires and health exams from 201 workers in a local electronic company during September 2004. Data analysis was done with SAS 9.1 for descriptive statistics and PC-LISREL 8.54 for covariance structural analysis Results: The overall fit of the hypothetical model to the data was moderate, it was modified by deleting five paths. The modified model had a better fit to the data($x^2=504.23$(p<001, df: 180), $x^2/df=2.80$, GFI=.95, RMR=.07, NFI=.90, PGFI=.64). Health behaviors and psychosocial distress were found to have significant direct effects on the cardiovascular disease risk factors. Self-concept had direct effect on psychosocial distress or health behaviors. Self-concept, work environment, and work condition had direct effect on social support. Work environment had indirect effect on psychosocial distress. Social support had indirect effect on health behaviors. But work environment and work condition were found to have little direct effect on health behaviors, psychosocial distress or cardiovascular disease risk factors. Conclusion: A cardiovascular health promotion program should therefore include psycho-social factors as well as health behavioral determinants in worksites.
